Abstract : in this paper , a kind of technological scheme for one - step precision forging spur gear with large module is put forward by using positive friction role . experiment , in which commercial pure lead is taken as test material , is done in the special die designed , and force vs . stroke curve is recorded . it is shown that positive friction role can efficiently make a contribution to the filling of the tooth cavity , but increase forming force 文摘:针对大模数直齿圆柱齿轮，提出了利用积极摩擦一步成形的工艺方案，并用工业纯铅作为试验材料，在设计的专用模具上进行试验，记录了力? ?行程曲线，结果表明：利用积极摩擦作用能够有效地保证直齿圆柱齿轮精锻时齿腔充满，但同时增加了变形力。

The result presents , it is relatively useful for filling in the tooth cavity of big modulus 、 high thickness spur increase to increase suitability height mount piece , and the load of forging spur gears can be decreased by adding a mandrel , but unit area forging force does not cut down , and it has a little influence on filling in the tooth cavity 结果显示，增加适当高度的镶件对大模数、高厚圆柱直齿轮齿腔填充比较有利，增加芯棒可以降低齿轮成形载荷，但单位面积的成形力并未减少，且对齿轮的填充性影响不大。
